RoCE

Use the UI or CLI to monitor RDMA over Converged Ethernet (RoCE) for Spectrum switches and BlueField DPUs.

RoCE Commands

• netq show roce-config

View RoCE Counters Networkwide in the UI

RoCE switches displays transmit (Tx) and receive (Rx) counters as well as counter pools for all switches running RoCE in your network. RoCE DPUs displays physical port, priority port, RoCE extended, RoCE, and peripheral component interconnect (PCI) information for all DPUs running RoCE in your network.

1. From the header or Menu, select Spectrum-X, then RoCE.

2. Select either RoCE switches or RoCE DPUs. The following displays a list of all switches running RoCE across a network.

View RoCE Counters for a Given Switch

You can view the following RoCE counters for a given switch:

• Receive and transmit counters
• General, CNP, and RoCE-specific counters
• Counter pools
• Port-specific counters

To view RoCE counters on a switch, search for the device’s hostname in the global search field or from the header select Add card > Device card. Select a switch that is running RoCE and open the large card on your workbench. Click the RoCE tab to view RoCE counters and their associated ports:

Expand the card to the largest size, then select RoCE counters from the side menu. Use the controls above the table to view, filter, or export counter statistics by Rx, Tx, or Pool.

Disable RoCE Monitoring

To disable RoCE monitoring:

1. Edit /etc/netq/commands/cl4-netq-commands.yml and comment out the following lines:

    cumulus@netq-ts:~$ sudo nano /etc/netq/commands/cl4-netq-commands.yml
   
    #- period: "60"
    #  key: "roce"
    #  isactive: true
    #  command: "/usr/lib/cumulus/mlxcmd --json roce counters"
    #  parser: "local"
   

2. Delete the /var/run/netq/netq_commands.yml file:

    cumulus@netq-ts:~$ sudo rm /var/run/netq/netq_commands.yml
   

3. Restart the NetQ Agent:

   cumulus@netq-ts:~$ netq config agent restart
